Jennifer Aniston, Justin Theroux reportedly planning ‘small’ wedding

Jennifer Aniston and Justin Theroux, who were spotted together at the Oscars Sunday, are reportedly in full wedding mode, preparing for a “small affair” that is set to take place very soon.

People magazine’s cover story suggests that the couple have already set a wedding date and chosen wedding bands. She’s also started looking at wedding dresses.

“It will be a small affair with their closest friends,” the magazine’s source says. “Jen seems more confident than ever...and they've become a great team.”

Aniston is currently filming an untitled Elmore Leonard project with Tim Robbins in Connecticut. Once production wraps up on that film next week, the former Friends actress and her Wanderlust co-star are expected to have their wedding.

While Aniston may be happy with Theroux, a report from RadarOnline suggests that she has become very difficult to work with on the film set.

“Every day at lunch the entire cast and crew head to a cafeteria facility where they all sit down and eat lunch together for well over an hour,” an insider told the site. “But the only person who doesn’t eat with everyone else is Jen. She quickly grabs a lunch to go and leaves.”

The insider described ‘diva’ behavior that also included parking her private trailer “miles away from the set.” The source added, “Her behavior is a clear indicator to everyone that she’s not approachable.”

The film is based on a novel by Jackie Brown writer Elmore Leonard and is being directed by Daniel Schechter. It’s set for release in 2014.
